Abstract

PURPOSE: To allow systems to share data bases with a small communication overhead by providing plural data processors with subsystems which access common data resources respectively and lock managers.
CONSTITUTION: Respective host computers 1W3 include operating systems 11W13, lock managers 21W23, and subsystems 31W36 one to one and common data resources are stored in common file devices 61W66. The common file devices 61W66 are connected to the host computers 1W3 and the subsystems 31W36 send lock requests to the lock managers 21W23 to acquire locks for the common data resources and then access the common data resources through the operating systems 11W13. The locks are made in block units. The subsystems 31W36 are equipped with buffer pools 41W46 and journal files 51W56.
